Inventor: ENOMOTO KUNIO
IPC: F16L57/00
Filed: 1982-06-02
Abstract: PURPOSE:To facilitate detection of minute leakage, by providing two types of hermetically sealed pipe structures in the vicinity of weak points of piping such as welded parts. CONSTITUTION:An outer pipe 46 is attached to annular protruded parts 44, which are attached to the outer part of a pipe 41 in the vicinity of welded part 42 by bolts and nuts 44. A rupture disk 48, which is broken when the pressure of leakage detecting fluid 47 filled in a gap formed by the pipe 41 and the outer pipe 46 becomes larger than limit pressure, is provided in the outer pipe 46. A minute leakage detecting sensor 49 is provided in the vicinity of the welded part 42. Even though cracks are generated at the weak point 42 such as welded parts of the pipes and working fluid 43 leaks, the leakage can be detected by the sensor 49 while the amount is minute because the space is hermetically sealed. When the cracks are expanded and the amount of leakage is increased, the pressure of the leakage detecting fluid 47 is increased, and the rupture disk 48 is broken. Even though the cracks are further expanded and the pipe 41 is separated therefrom, the pipe is constrained by the outer pipe 46, and damage of neighboring equipment is not caused.

Title: Heat developable color photosensitive material
Inventor: KOMAMURA TAWARA
IPC: G03C7/00
Filed: 1984-05-09
Abstract: PURPOSE:To obtain an image high in the max. image density and free from fogging by forming a photosensitive layer contg. silver halide, an org. silver salt, a dye donor, a reducing agent, and a Co(III) complex salt. CONSTITUTION:The photosensitive layer formed on the support contains at least the silver halide, org. silver salt, dye donor, reducing agent and Co(III) complex salt. The use of such the Co(III) complex oxidizes Ag of fogging nuclei and destroys them. The complex itself is reduced or allowed to release ligands with heating, and pH of the system is raised with such released ligands to restrain development of silver. Moreover, a diffusive dye produced in the early stage of the development can be transferred completely by heating for a long period, and fogging is prevented even in pH hightened in the later stage of the development because the silver development is stopped. Only Dmax can be raised even in development at high temps. or for a long period without rise of fogging by using such the photosensitive material. It especially favors the case of using a multilayer structure, because sufficient transfer can be executed from the lowest layer.

Title: Optical information recording medium
Inventor: KOTAKA KAZUHIRO
IPC: G11B7/24097
Filed: 1990-04-12
Abstract: PURPOSE:To secure the reliability extending over a long period without generating a harmful effect caused by a hub by constituting an optical disk of automatic centripetal structure parts without fixing the hub to the optical disk. CONSTITUTION:Both of a substrate and a hub are not fixed but are in a state that they can move freely in a space generated by sticking the substrate. Therefore, a harmful effect caused by fixation is not generated. When this optical disk is placed on a recording/reproducing device, the hub which is not subjected to constraint at all before it is placed is constrained by a rotary shaft fitted into the center hole, and also, constrained by a magnet provided on a turntable. Binding force by the magnet is transmitted to the center hole of the substrate through a tapered collar, and becomes binding force of the substrate and the turntable. At the time of transferring this binding force, a centriperal action is generated automatically between a guide group and the hub, and the centripetal action of the rotary shaft of the turnable and the guide group is executed.

IPC: B41J2/01
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To eliminate degradation of image quality due to inter paper fluctuation by preventing fluctuation of inter paper distance at the time of recording and fluctuation of inter paper distance due to instability of behavior at the forward and rear ends of a material to be recorded. SOLUTION: The ink jet recorder is constructed to control the separating/ approaching operation of a platen 11 based on the detection signals from sensors 9, 10 for detecting the end of a material to be recorded such that the platen 11 is separated from a carrying face after the forward end part of a material P to be recorded is clamped by a pair of paper discharge rollers 7, 8 and the platen 11 is brought close to the carrying face before the rear end part of the material P to be recorded is released from a pair of carrying rollers 5, 6 after the recording proceeded. Since the platen 11 is located along the carrying face when the material P to be recorded is carried on the platen 11, stabilized carrying state and inter paper distance are ensured.  At other time, the platen 11 is retracted from the carrying face and separated therefrom even if the material P to be recorded is waved through swelling after recording, and thereby the material P to be recorded is prevented from floating to rub a recording head 2.
